WINDING MACHINE.

Appiieatioii iiled nayei, 1923. serial No. 642,687. j

To all 'Lo/0m t may concern.'

,Be it known that I, NICHOLAS E. GIBSON, a citizen of ythe. UnitedStates fof America, residing in Chicago, county -of Cook, .and State ofIllinois, have invented kcertain new and useful Improvements in VindingMachines, of which the following is a speciiioation.

My invention relates in general to winding machines, such as are usedfor winding bobbins or coils, and Vmost particularly to that class ofwinding machines forwinding .small clectromagnet coils used Iinconnection with telephone receivers and the like. An object f Vof myinvention is the provision of .an improved winding devi-ce which isauton'iatic in its reciprocatory movement, simple in construction andpositive in its operation.

Electromagnet coils` of the type used in receivers and for various otherpurposes are small and are usually wound ofy ine gauge wire so that amaximum number of vturns of wire may be placed in a minimum space.

More or less trouble is'eXperieif-iced in winding coils of this Vtypefor the reason that when the wire reaches the lend of the spool, thatis, upon the completion of a layer of turns, the wire piles up at thestart of each new layer at the ends of the spool, ,due -to lthe.factthat most of the coils .of this type are .wound by hand and thedwell at the start of each new layer is prolonged, permitting the wireto pile up before the natural rate of feeding takes place across thespool.

This piling up of the convolutions at each end of thespool produces apronounced bulge or lump which makes the threading of the outer terminalof the winding through the spool head diflicult, due to the 'bulge whichat times completelycovers this opening.

To overcome this 'objectionable feature, I have .designed a Windingmachine which eliminates this through the provision oii .a reciprocatingmember wliichtravels to and fro, and a? feature of my invention is theprovision of a tripping anec'hanism in which the instant that a layer ofthecoil beiiigwound is ceiiipleted, the movement of the reciprocatingmember `is reversed to permit- :the travel of the reciprocating feeding`member to start back vin its reverse direction. 4'Ilie tripping meansfor instantly reversing the direction of travel of the reciprocating.meinber prevents the `wire at .the beginning.ciL a 4with a tensiondevice Y die device Z.

new layer `piling up, thus `producing a smooth coil. Y

Another feature of my invention is the provisiony `Of a novel clutchmechanism in operative relation with the reciprocating member justAdescribed to bring about the automatic reversal of travel of thereciproeating member.

Still another feature ,of my invention is the provision ofnovelsupporting means for a shaft whic-li I will term a floating shaft andits adjustment in relation with the reciprocating member so that thesaid member may be adjusted to trip at the desired instant.

The above features, as well as others, will be more fully described inthe ensuing speci-A cation. f

From Ythe drawings and the description, it may be seenthatihrough the agency `ofthe gears 10,

and 22, the clotchndislc' ot the' clutch C rotates fin the ,direc-tionais indicated thereroin,and that :through the a'gencj) f @116g '5 1,5and 35 Athe disk ,5.0 .cog te durch The legs 86 and V87V C yrotates inadirection opposite to the drection of r:the -rotationcf the disk 18 ofthe clutch C, Vith reference to Fig. 1, the disk as already described,and theclntch dis-lr '8O and :the gear sec-nredto its sleeve extension33 rotate about the aligning bearings 36S which -ixotates in 4the samel.direct-ion as the s'hait 17, diie to the :threaded `connection betweenthe 'threaded end 25 of the shaft '17, and the threaded portion of theorifice 37 .of the aligning' bearing' 86 ivitlrno etlect at this time.The block i5 which iis in threaded Iengagement with `the member d4 newstarts rrael to the lett, ldue to thethreaded connection between memberslll and L1.5, and diie -to the biturcatedend ot the reciprocatingmeinber R straddling the block d5, the member R as a whole travels tothe lett sliding along;` the shai-t 2. The linlV connect-ion 72 is nowswing abontits pivot 10, due ito thc slot 76 and pin 77 connectionbetween the said link 72 and member R, and its end 71- is tlrus movedtothe left, and its other end 75 ivill; o1: 'course swing' to therigl-rt and as .the coil springSG has its one end secured to the end 75otlthe link 72 and its `other end secured to the Vear 78 ot the member52 secured to Lthe block 51 supported on the rod thftliesprin-g Awill beplaced under tension. The block -51 which is s-lidably supported on therod 50 is heldin its position as clearly illust-rated in Figs. 1 and L1,due to the tact thatthe plate extension 92 of the block 51 rests in thenotch 90 of the lee' 88 of the member 82, this member 82 being held inthis` position by means of the coil spring connection 921betiveen thetwo members 82 and lThe connection .between the plate 92 and the notch.90 ot the member S2 also holds =the l member 51 and its supported partsin the position illustrated in Fig. 1 with the disk 57 Vin meshlwiththeclntcli disli 1S nntil released as ivi/ll presently be described.iks-the reci procating` member R continues its travelyto the deft, itsyadjustable member #19 .will `engapfge vthe 'of fthe, 'SG the member S2-a ,M canse it to -rocli about its pivot 84, `tglrus movingthe leg 86,tothe lett and 'its leg 'BS upward The continued travel ot the memberto the lett causes the end 7 5 of the link 72 to swing 'to the righ-tVto .place the spring Sdugnder-gtension', and at the sanjie gtigmge lthe leg 86 of the member 82, the said member 82 is rocked about itspivot 84 to cause the leg 88 of the member 82 to move upward. Theinstant that the nose 100 of the notch 90 in the member 82 disengagesthe edge 101 ofV the plate extension 92 of the block 51, the tension ofthe springpulls the block 51 and its supported parts as a whole to theright along the rod 50, and due to the connection between the disks 57and 58 and block 51 and its members 52 and 53 secured to the block 51,the disk 57 will also be moved to the right along the square p0rtion 2 3of the shaft 17 out of engagement with the clutch disk 18 of the clutchC. The block 51 having moved to the right the plate 92 also moves withit, and when the edge 102 of the plate 92 passes the nose 103 of thenotch 91 in the leg 89 of the member 83, the said member 83 is caused torock about its pivot due to the tension of the coil spring 94, and thusforce the leg 89 of member 83 downward to permit the plate 92 of theblock 51 to rest in the notch 91 in' the leg 89 for purposes as willpresently be described.

The U-shaped member 56 secured to the block member 51 is also moved tothe right, and due to its connection with the disk 58, it is also movedto the right into engagement with the clutch disk 30 of the clutch C.

The disk 58 now being in engagement with the clutch disk 80 of theclutch C', and as the said clutch disk 80 rotates in a directionopposite that of the clutch disk 18 of the clutch C, due to the gearingconnections 15 and 35, the shaft 17 is now rotated in a direct-ionopposite that when the member traveled to the left, and due to the con-.nection between the reciprocating member R and the threaded member 44on the shaft 17, the said member R now travels to the right causing thelink 72 to be rocked about its pivot 73 causing its end 74 to move tothe right and its end 75 to the left to place the spring 81 connectedbetween the member 5G and the link 72 under tension. The block 51 andits supported parts remain in the position it was moved to as justdescribed by means of the spring 80 due to the plate. 92 of the saidblock 51 resting in the notch 91 in the leg 89 of the member 83. In itstravel to the right, the adjustable member 49 of the reciprocatingmember R engages the leg 87 of the member 83 and causes the said member88 to be rocked about its pivot 85, moving the said leg 87 to the rightand its leg 89 upward. Now when the nose 102 of the notch 91 in the leg89 of the member 83 disengages the edge 103 of the plate 92 of the block51 the spring 81 which was placed under `tension dueto the movementofthe end 75 of the link 72 to the left, now pulls the block 51 and itssupported parts to the lefty-@using the disk S1-*.30 disengagd lill@clutch disk 30 of the clutch C and move the disk 57 of the clutch C intoengagement with its clutch disk 18. The member 82 now rocks about itspivot 84 permitting its leg 88 moving downward, permitting the plate 92to again rest in the notch 90 in the said leg 88 of the member 82, andwhen the mechanism is in this position, the reciprocating member R isagain ready to start on its travel to the left.

The distance of travel of the reciprocating member R from left to rightand vice versa is controlled by means of the adjustable thimbles 49 and49 threaded in the member R. Then the thimbles 49 and 49 are turned tobring them closer to the legs 86 and 87 of the members 82 and 83, thedistance of travel from left to right and vice versa is shortened, as isreadily apparent from the drawings and description. The floating shaft17 is also adjustable to the left or right so as to place the threadedmember 44 secured to the shaft 17 in its correct position so that thetravely each way of the reciprocating member R from its center is thesame. rlfhis adjustment may be accomplished by loosening the lock screws42 and 43 and turning the aligning bearings 26 and 36 to move the shaft17 and its supported member to the right or left as the case may be toplace the said threaded member 44 in proper position in relation to thereciprocating member R so that the said reciprocating member R travelsequal distances to the right or left from its center. Vhen thisadjustment of the member R is secured, the lock lscrews 42 and 43 areagain tightened to lock the shaft 17 and the bearings 26 and 36 in theiradjusted position.

The reciprocating member R has secured' to it by means of suitablescrews 110 a plate 111 which carries a post 112 secured to a hingedmember 113. An arm 114 adjustably secured to the post 112 is providedwith a suitable looped end through which the wire passes from the supplyspool to the bobbin or coil that is being wound.

From the detailed description just given, it may be seen that thewinding mechanism is provided with a positive trip mechanism which istripped the instant that a layer of wire is completed to permit thetravel of the reciprocating member R in a reverse direction, and thistrip also cooperates to the clutch mechanism C and C so that the instantthis trip occurs the direction of travel is reversed. With this positivemeans of tripping and reversal of travel of the reciprocating member, Iam enabled to produce a far superior coil than that produced by means ofthe hand operated method.

In Figure 9 the device Y is a tensioning device controlling the supplyspool of wire, an'd the device Z is the winding spindle which support-sand. rotates the bobba to be ama-92a -v Wound. Thel device-,Xautomatically feeds the-Wire tothebobbin or spool carried by Z.-
